May. '07 Copper-based Solar Cells: Good for the Environment, Good for the Consumer Copper has long been used in solar heating/hot water systems, where it is commonly used in heat exchangers. Now, it promises to become equally valuable in photovoltaic (PV) systems. These systems produce electricity through the action of sunshine on certain semiconductors, including so-called thin-film materials and the currently most promising material: copper indium gallium diselenide or CIGS.
Sep. '06 High Copper Alloys - High Strength Coppers for Demanding Electrical Applications For many electrical applications, the demands of electrical technology require copper to have higher mechanical properties and to be capable of use at elevated operating temperatures while still retaining the good conductivity for which it is selected in the first place. The copper industry has invested much research effort over the years to create materials capable of meeting these demanding needs. The products of this research are found in the large variety of high copper alloys, materials whose properties are equal to or, in some cases, higher than those of many other engineering metals, yet, which have conductivities high enough for electrical applications.
Jul. '06 Copper Makes Beer Better: Control of Hydrogen Sulfide in Beer with a Copper Electrolysis System Hydrogen Sulfide (H
2S), a volatile sulfur compound, is a normal byproduct of the fermenting process. But, research has shown that people are very sensitive to the odor of H
2S and can detect this odor as an off-flavor at very low concentrations. Researchers have found that the most effective means to control H
2S is by using copper which removes the H
2S as copper sulfide (CuS) which can then be removed from the final product.
Jan. '02 The New Economy The transition from an industrial to an information-based economy could increase our reliance on copper.
Sep. '01 Die-Cast Copper Motor Rotors Heading for Success A look a the on-going research designed to take advantage of copper's high conductivity in such a way as to enable the creation of ultrahigh-efficiency electric motors being conducted by an industry-government consortium of which the Copper Development Association (CDA) is a member.
Aug. '01 Introduction to Copper: Applications This article is intended as an introduction to copper, describing the many ways in which the metal is so useful. The article also touches on copper's invaluable contribution to the health of plants, animals and mankind.
Sep. '99 Transformer Innovations Although they have no moving parts, transformers stand outside for an average of 40 years and thus experience considerable stress. Look at a series of recent innovations in the way copper is fabricated that have greatly improved transformer design, manufacturing processes and performance.
Sep. '99 Transformers Can Contribute to Global Warming Goals Increased attention is being focused on the savings energy-efficient transformers could make on a national scale in the US and Europe and their potential contribution to meeting internationally agreed goals for reducing global warming.
Jul. '99 The Copper Motor Rotor: New Technology for High Efficiency Motors A look a the on-going research designed to take advantage of copper's high conductivity in such a way as to enable the creation of ultrahigh-efficiency electric motors being conducted by an industry-government consortium of which the Copper Development Association (CDA) is a member.
